Solar-Log™ terminal strip connector RJ45 inverter
Terminal PIN
► 1+ ► 3+ T/R
► 3 ► 7 RTN
► 4- ► 5- T/R
2. Insert the RJ45 plug into the RJ45 IN socket on the first inverter.
3. Terminate the inverter if no additional inverters are to be connected:
Set the DIP switch for the terminal resistor to ON.
4. Insert the terminal block connector into the Solar-Log™ RS485 socket.
Connect the inverters to each other
•
Connect using the RS485 data cable with RJ45 plug;
Connection cables between the inverters are supplied with the inverters. Use these.
•
Where to connect: RJ45 socket on the inside of the inverter.
Procedure
1. Insert the RJ45 plug into the RJ45 Out socket on the first inverter.
2. Insert the other end of the cable into the RJ45 In socket on second inverter.
3. Connect the other inverters to each other in the same way.
4. Terminate the inverter if no additional inverters are to be connected:
Set the DIP switch for the terminal resistor to ON.
Assign the communication address
1. Recommendation: Continuous numbering starting with 2.
Address range 2 - 63.
2. Setting: Start according to the inverter‘s instructions.
Note
The inverter address settings are configured with the „Aurora Manager LITE“ software. (Refer to the
manufacturer‘s manual)
Note
The inverter has two RS485 communications ports. „Modbus“ has to be defined as the protocol. The
default protocol for both ports is „Aurora.“ This can be modified with the „Aurora Manager LITE“ soft-
ware.(Refer to the manufacturer‘s manual)
Note
The communication has to be terminated on both ends of the bus.
